ESPHome: DIY Irrigation Controller With Internal Scheduler

Tags: #<Tag:0x00007f32664e5148>

I programmed a Sonoff 4 Channel Pro R2 with ESPHome to replace a flaky off-the-shelf battery powered irrigation controller. I am especially proud of the lambda functions I was able to put together to run the schedule on the Sonoff. Avoiding reliance on Home Assistant automations allows me to program and restart Home Assistant all I want without worrying about interrupting an hour long pool fill, or even worse causing the water valve to remain open indefinitely!

The buttons on the Sonoff can be used to manually start a zone, but I also created a use Interface for monitoring and editing the schedule for each zone.

Anyway, if you are interested in learning more about how I did it, I go into a lot of detail in an article on my blog (link below). If you prefer you can go straight to the source code on Github (irrigation.yaml & irrigation.h).

Thank you to Home Assistant Community members: @jlax47, @nickrout, @glmnet, and @risk, as well as @broxy70’s countdown code.

Thanks for the thanks, but I don’t think I did all that much to help!

Pretty cool project. I found it via web search then found all the links to the usual places I haunt (esphome, this forum, github).
It’s also pretty cool that you learned enough coding to make the lambda’s and header file. Even inspirational, I’d say.

I took your code off github and expanded it to support 4 zones. I had an old 4ch lying around so I loaded it up and ran it for a while, then installed it all in a nice case, mounted on the wall, conduit to the valves, etc. I hooked up the last valve today and found the interface on home assistant constantly changing to ‘unavailable’. Then when I went outside, even manual presses of the buttons on the 4ch were laggy and often did not work. The unit would appear to lock up and reboot regularly too.

I saw in your github issues you were testing stability. Did you have stability issues with it ever? I’m wondering if 4 zones is more than it can handle. It seems like it worked better before I expanded your code out from 2 zones to 4 zones. But it’s also a hot day (high of 105 deg F) and even though the controller is in the shade, it may have overheated. I’ve left the cover on it’s box open to provide some airflow but that’s little help with outside temps so high.

This thing has been rock solid, 295 hours of uptime since my last code update! It never seems to go down unless I push a code update to it. I may have an unfair advantage as I have a commercial grade UniFi wireless network setup with 3 wireless access points, including one inside a closet about 10 feet from my Sonoff. For reference mine is reporting a -76db signal strength.

You could always remark out all of the code for 3 of the zones to test your theory about 4 zones being too much. I don’t know. I left that code out to make maintenance easier, since I didn’t need any more yet.

Thanks for the reply. I did exactly what you suggested and commented out the extra code, just turning it into a basic set of relays and it still had problems falling offline. In fact, I have a sonoff basic that runs an exhaust fan in my server room and it was having the same problem. After moving it to tasmota, all problems went away on both units. Maybe something going on with my esphome setup? For now I’m happy just using them with tasmota.
I have a unifi ap’s as well and signal strength was very similar.
It’s still an awesome setup. Thanks for publishing it all. My garden loves you. Seriously, the plants look better than ever.

Hi, based on Brian’s work, i added support for scheduling irrigation for different days of the week.

Here is the modified irrigation.h (i modified other parts too based on a border-case test)

#include "esphome.h"
using namespace std;

// Declare functions before calling them.
bool scheduled_runtime(string);
string update_next_runtime(string, string);

  int time_hour = time_now.hour;
  int time_minute = time_now.minute;
  int time_wday = time_now.day_of_week; //added for day scheduling

  //Prevent program crash - functions were created specting a time formated string
  // if you pass "now", program crashes in certain cases.
  if (time == "ahora") { //"now" in English, customize according to your prefs.
    return false;
  }

  // Split the hour and minutes.
  int next_hour = atoi(time.substr(0,2).c_str());
  int next_minute = atoi(time.substr(3,2).c_str());  int next_wday = 0;
  string day = time.substr(6,3).c_str(); //day text is added to original string

// Converting days to week numbers, change text based on your Language
    if (day == "Lun" || day == "lun" || day == "LUN") {

I had the same problem rebooting every min, dug and looked very intently at ESPhome and the yaml but guess what, the only problem I found was I didn’t add duration times or start times to the sensors so when the time component in ESPhome was looping @1min it would crash. The good part was I took the time to move it away from API: and use MQTT like I wanted. :slightly_smiling_face:

Expanding to 12 zones then maybe I’ll attempt the date thing @raberrio did but I’m dumb and only know English so google translate will be my friend. :crazy_face:

Thanks @BrianHanifin Nice Job!! I read this write up when you did it at first but didn’t want it in the API side but now got what I want just gotta clean up what I did and I’ll share what it is. Not much different!

Jeff i mentioned that crash in my post, according to my research is because you pass the value “now” to the custom function that is waiting a time formatted string.

I fixed it in my code.

good luck

Hi Rob! How are you? I have used your code, but I am having problems with the device rebooting and I cannot configure the duration time, it says that it is not available. Could you please indicate which is the change I must make for this to work?
and I also have doubts with the format of the time zone. I am from Argentina
greetings and thank you very much

I had the same problem as Joaquin. Looking at it further made me realize you need to define the input fields in your configuration.yaml. Here’s what I created.

input_text:
irrigation_zone1_times:
name: Zone 1 Time Periods
initial: 01:00
irrigation_zone2_times:
name: Zone 2 Time Periods
initial: 01:00
irrigation_zone1_days:
name: Zone 1 Days of the Week
initial: Mon,Wed,Fri
irrigation_zone2_days:
name: Zone 2 Days of the Week
initial: Mon,Wed,Fri

input_number:
irrigation_zone1_duration:
name: Zone 1 Duration
initial: 3
min: 1
max: 30
step: 2
irrigation_zone2_duration:
name: Zone 2 Duration
initial: 3
min: 1
max: 30
step: 2

First I want to thank Brian for taking the time to post his project. It’s pretty cool.

As I didn’t have a Sonoff I went this route. https://khaz.me/cheap-and-easy-control-of-8-relays-through-home-assistant/

I modified Rob’s YAML and .h (posted above as he had included the days option) so that it would work with 3 Zones and changed it to English.

Here’s my changes if anyone is interested;

Hi Viking I’ will try later this afternoon.
Thank a lot

HI! I made the corrections of imput_text and imput_um and now the values ​​appear, but I cannot modify them. any ideas?

I suspect your problem might be the timezone setting. I had the same initial problem but changed mine to timezone: EST+5EDT,M3.2.0/2,M11.1.0/2 (I updated my previous post).

I referred to the ESPHOME Documentation and it says this,

  • timezone ( Optional , string): Manually tell ESPHome what time zone to use with this format (warning: the format is quite complicated) or the simpler TZ database name in the form /. ESPHome tries to automatically infer the time zone string based on the time zone of the computer that is running ESPHome, but this might not always be accurate.

I suspect you could comment it out so it picks it up from HA.

A couple of things I realized when testing this out. I put initialize values on the input fields that I defined in the config. Not a good idea as these get set every time you restart HA. I also changed a few ICONS to make things a little easier to understand. Here’s an example of my display in HA.

Hi Viking! I realized that the values ​​I was entering in the days field were in English and I configured it in Spanish, by mistake it never started :blush: . So now it works :smiley: .

For the record, time_zone was corrected too.

time:
  - platform: homeassistant
    id: homeassistant_time
    timezone: America/Buenos_Aires

But … How did you solve the problem that the fields were not saved when the HA restarts? Same here :frowning:

Once again…THANKS

Hi it´s me again, well…i remove initials values and it worked!

Do you mind share the entities card code and where did you change the icons?

thanks again

Here’s my Lovelace YAML for Zone 2

type: vertical-stack
cards:
  - type: entities
    entities:
      - entity: input_text.irrigation_zone2_days
      - entity: input_text.irrigation_zone2_times
      - entity: input_number.irrigation_zone2_duration
      - entity: sensor.zone_2_next_watering
    title: Backyard Zone 2 - Schedule
  - type: entities
    entities:
      - entity: switch.irrigation_zone_2
        secondary_info: last-changed
        name: Zone 2 Watering
    title: Backyard Zone 2 - Watering
  - type: history-graph
    entities:
      - entity: switch.irrigation_zone_2
    hours_to_show: 24
    refresh_interval: 0

On the input parameters you can define a icon see my example below.

input_text:
  irrigation_zone2_times:
    name: Zone 2 Time Periods
    icon: mdi:chart-timeline
  irrigation_zone1_days:
    name: Zone 1 Days of the Week
    icon: mdi:calendar-week

input_number:
  irrigation_zone2_duration:
    name: Zone 2 Duration
    icon: mdi:timer
    min: 2
    max: 60
    step: 2  

Within the ESPHOME Irrigation Yaml you can also define ICONS, see example

  - platform: template
    name: Irrigation Zone 2
    id: irrigation_zone2
    icon: mdi:sprinkler
    lambda: return id(relay2).state;
    optimistic: true
    turn_on_action:
      # Turn on if not disabled.
      if:
        condition:
          lambda: return id(irrigation_zone2_duration).state >= 1;
        then:
          - switch.turn_on: relay2
    turn_off_action:
      - switch.turn_off: relay2
